Mr. David Bradley;
thank you very much but?how also can i make the heat pump(water -water heat pump) to take 2 sources of water from 2 separated storage tanks? and what type of heat pump does support that?
best regards.
Mohammad,
?The simplest way would be to define two equations one of which has a value of 1 during the time period when you want to allow cooling and the other of which has a value of 1 during the heating time period. For example:
isSummer = AND(GT(TIME,3000),LT(TIME,5000))
isWinter = 1-isSummer
You then connect the result of these equations to the appropriate heat pump inputs. The above equations would allow cooling between hour 3000 and 5000 of the simulation and would allow heating at all other times. You have to be a bit more careful with your equation if you want to run multiyear simulations.
kind regards,
?David
dear all ;
how can i control run this circled heat pump to work on heating mode in winter and cooling mode in summer.
best regards

Thank you for your prompt?response.
Unfortunately,?both?the restaurant?and the sunspace examples use?Type 15-6 and Type 15-2 ?(TMY-2). My problem is that when I replace to Type 15-1 (TMY), my heating demand is increased, but remains within the BESTEST range, while my?cooling demand is significantly below?the BESTEST results. That's how I concluded that most probably I am doing something wrong in the connection of the weather file and the solar radiation available in the building's surfaces.
Thank you for your help?anyway.
Kind Regards, Eirini

Subject: Re: [TRNSYS-users] Question on Type 15-1 (TMY Weather file) ? Dear Eirini, you can find an example in your TRNSYS directory under ?\Examples\Restaurant\Restaurant.tpf It also uses types 15 and 56? ? Best regards

Betreff: [TRNSYS-users] Question on Type 15-1 (TMY Weather file) ? Hello TRNSYS Users, ? I am trying to simulate a simple building (BESTEST Case 600)?and I am getting quite odd results. I believe that my mistake is in the connection between Type 15-1 (TMY Weather file) and Type 56 (Multi-zone building). I would like to ask whether there is any tutorial online or any example in the program's documentation folder?on how to connect weather files to Type 56 for multi-zone building simulation. ? Thank you. ? Kind Regards, Eirini ? Eirini Mantesi Research Engineer School of?Civil and Building Engineering Loughborough University T: +447462665904 E: E.Mantesi at lboro.ac.uk
